STREET-LAMP.

Specification of Letters Patent.

\ Patented Jan. 8, 1907.

` Application lled Februaryl, 1906. Serial No. 301,313.

Be it known that I, lFRIEDRICH RECH, a citizen of the Empire of Germany, residing at Ehrenfeld, near Cologne-onthe-Rhine, in the Empire of Germany, have invented a new which may be disposed Within or without the globe `or both at a time and are connected with the y'lampfpost in a" suitable manner, while the globe rests on a ringV securedon the said" arms or posts. For cleaning and replacing the globe and the parts of the burner of suchja street-lamp it `was hitherto necessary to turn up either the whole roof or a I part of the same, since theAgas-conduit below, more particularly thebroad supportingring, rendered the interior of the lamp inaccessible from below.v ,The cleaning of the lamp from above after turning-u the roof or a part of the same is, however, o jectionable for various reasons.

lf the whole roofl were to be turned up and the heavy globe were to L be lifted from its seat, this would `be a most diicult task, especially in winter, when the hands of the lamp-trimmer Iare quitey stiff fortable and thorough cleaning.

with cold. If, on the contrary, only a part vofthe roof were to be turned up and if the lamp-trimmer were to put his hand through the opening for cleaning the internal parts` and the globe, the space between the burner,

the. incandescent mantle, and theI globe would be far too narrow to facilitate a com- My invention relates to improvements in vstreet-lamps whereby the `said vinconveniences are avoided and a thorough cleaning of theinterior of the `lamp is rendered easy and Y possible.

The'objects of my improvements are, first,

l to form a sufficiently long .partof the lampfor lighting the gas in an easy manner.

trated in the accompanying drawings, in which l Figure 1 is an elevation of the street-lamp `and a part'of the lamp-post, partly in section.

Fig. 2 is a horizontal section through the line A Bin Fig. 1. Fig. 3 is a side view of a part of the lamp-post on the same level with the same part in Fig. 1. Fig. 4 is a vertical longitudinal section, on an enlarged scale, through the gas-conduit shown at Fig, 1; and Fig. 5 is a vertical longitudinal section through a modification of the upper part ofthe lamp-post and of the gas-conduit.

y Similar letters of reference refer to similar parts throughout the several views.

A socket e is arranged to be fastened. on the upper end of the lamp-post 7c in Fig..1 and is made mostly cylindrical. It serves for supporting on a shoulder near its up end a ring h and on another-.shoulder s belp aring b. The ring h is rigidly connected with several (here two) vertical arms ff and may be secured on the socket e in any known manner, be it by means of a set-screw .(not

arms f f are arranged for supporting a roof construction, the only essentialpoint. being thatv it be provided with an opening or a flange al, in which the upper ed e of a globe a can engage and by which theatter is protec'ted from horizontally shifting under .the action of any wind orstorm. Thering I) is to'support the globe a.' and is rovided with severa a corresponding number of projections m 4fm on the socket' e can pass. The ring b is ,moreover, provided with several (here four) pairs ofgnosesA n n and with several air-holes .i i. Thelopening c of the ring b is made slightly larger in diameter than they guiding part of the' socket e.

It will be seen that the ring b can be turned and brought into such a position in'which the projections my fm canl pass 4throughits cuts o o if it is moved upward on the socket e. Above the projections m m the ring-b can 'be turned througha' convenient angle (here forty-five degrees) until the projections m' m can engage between its noses n fn, whereupon (here four) cuts o .0, t ough whichv shownlor by means of ascrew-thread. rThe the ring is moved a little downward untll it rests on the projections mm. Then theown tain these objects by the constructions illusl weight ofthe ring b and the globe' a will prevent these parts from shifting Iupward and the noses it n will prevent the ring troin turning i111. this. Simple/,meneer 1the ring t with the globe a can' be secured in the upper 5 position. Y

The socket e is provided with aT-slot e5, in which the 1key e3 of a specialgas-cock can engage. "The 'latter is of a construction shown at Fig. 4.
